Depressed Symptoms

Online depression communities offer people with depressed symptoms new opportunities to obtain health information and provide social support for each other to fight against the depression. We sought to investigate whether usage of online community help improve depression outcomes and determine which types of usage behaviors have positive or negative effects on depression. We proposed that two dimensions of the sense of belonging (sense of identity and trust) and three dimensions of the sense of support (informational, emotional, and socializing) have significant effects on depression, and further considered gender difference and its effect on depression. We obtained a dataset consisting of 465,337 posts from 244 members from a popular online depression community to test all 10 proposed hypotheses. The results reveal that (i) the sense of shared identity, trust, informational support, and emotional support have positive effects on depression, while socializing support have negative effects on depression, and (ii) the sense of shared identity and trust have more positive effects on depression for female users than male users while socializing support has a more negative effect on depression for female users than for male users. The findings have important practical implications for designers and managers of online depression communities.

Many service encounters are moving from traditional physical interfaces to technologically incorporated self-service options. However, it is surprising that very limited extant literature is devoted to understanding the movement towards self-service technologies. Therefore, this study aims at understanding customer value co-creation intention, practices including both the value co-creation and co-destruction and their co-creation experiences in self-service technology context. Based on the positivistic approach, a quantitative study carried out distributing self-administered questionnaires to 600 individuals chosen based on a non-probabilistic convenience sampling method. Study found that customer value co-creation intention has significant positive effects on customer value co-creation practices and significant negative effects on customer value co-destruction in SSTs. Value co-creation practices show a strong positive effect on customer functional experiences and ‘positive emotional experiences’ while having a negative effect on ‘negative emotional experiences. In contrast, co-destruction shows inverse relationships. This study assists practitioners to understand why customers collaborate with SSTs, what they do in co-creating value and how this links with their experience. Service providers can use this understanding to facilitate customer co-creation by securing positive customer experiences and achieving competitive advantage by designing and delivering value enhancing self-service technological interfaces from both strategic and operational perspectives.

Negative Effect

One of the chief complaints raised against sanctuary cities is that they can increase crime, while one argument in their favor is that they can increase the incorporation of Latino and immigrant communities. This chapter analyzes both the positive and negative effects of sanctuary polices, finding that these policies have no effect on crime rates when comparable cities are compared to one another and when crime rates pre/post sanctuary are examined. The findings show that sanctuary policies can have positive effects, potentially increasing both Latino voter turnout and police force representation. While sanctuary policies are found to have few downsides and potential positive benefits, antisanctuary legislation like Texas’s SB4 are found to have a negative effect. In high-immigrant areas, antisanctuary legislation is found to depress the number of 911 calls, suggesting that antisanctuary legislation does in fact reduce crime reporting, as opponents claim.

Purpose Purpose - The aim was to describe an improvement project and its effects on decreasing the time from diagnosis to treatment for patients with kidney stones and to reduce the negative effects related to untreated stones at one hospital in western Sweden Design/methodology/approach Design and methodology - A quantitative descriptive study based on Nolan’s improvement model was used. The quality improvement effects were evaluated using statistical process control (SPC). Findings Findings – Extracorporeal shock wave lithotripsy ESWL treatment’s positive effects within 48 hours were described as efficiency (decreased waiting time) from diagnosis to treatment, even if a re-treatment was necessary. The results also showed a reduction in the usage of percutaneous nephropyelostomies as a treatment option. Research limitations/implications Research limitations - This study includes data from one department at one hospital in one country. Comparative data include the time from acute radiological examination to final treatment but not total re-treatments, complications or time to up following radiological examination. However, the study was performed over one year and analyzed data from medical records in a systematic way. Practical implications Practical implications - This study may inspire measuring and developing routines from diagnosis to treatment for patients who are transferred within different departments at one hospital. Originality/value Originality - Studies in improvement projects considering ureteral or kidney stones are generally lacking; thus, this study is important for improving the care of patients with this diagnose.

Credit Contracts

How do suppliers of finance make sure that firm managers enforce credit contracts, or do not invest in bad projects? This approach is missing in corporate governance research. To bridge the gap, we take steps towards developing a stakeholder perspective with the focus on examining the effects of creditor participation in a firm’s top decisions, in relation to board performance. Based on a sample of 154 questionnaire survey responses from Nigerian public firms, after relating all measured items to every construct in the statistical tests of exploratory factor analysis (EFA), we employed the use of confirmatory factor analysis (CFA) in a structural equation modelling (SEM) approach for an in-depth analysis to estimate how well the stakeholder model fits the data. Building upon the construct creditor participation, and based on the proposed theory, we confirmed three dimensions – protect risk projects, protect collateral, and enforce contracts – to be confirmed measures of the latent construct. Significant creditors such as banks interfering in the firm’s board, especially in major board decisions, can reduce the potentials of managers to engage in high-risk projects. This has significant positive effects on the board’s role performance. However, items in the two dimensions – protect collateral and enforce credit contracts show weak measurements after EFA. The consequences are a new research agenda for boards has been set. The agenda will focus on the suppliers of debt finance, as significant to the firms akin with their equity shareholders’ counterparts. This will create knowledge; reduce conflicts of interests, and exploitation; and ensure equitable distribution of firm value. The approach exposes firms to access more inclusive strategic inputs especially on important and less risky projects that will yield better margin and sustainable growth. This may stimulate further debates on other stakeholder researches that are vital to debt financiers and boards, thus becoming actionable for practitioners in decisions on projects.

The study aims at shedding light on the positive and negative effects of social media on the lives of Muslim youths’ in Nigeria. although, it is an avenue to reach out to people, gather and spread information to one another in the Muslim domain. However, the youths have also lost their dignity through it, because it is another avenue for fraudulent activities. The work examines the effects of both electronic and print media on the socio-religious spheres of Muslim youths. The ability to use the media for “ networking” has played a significant role in the lives of these youths. As technology continues to evolve, including the means to connect and communicate in cyberspace, young Muslims see it as an opportunity for them to be heard. The researcher employed the use of qualitative and quantitative data analysis in carrying out this study as well as conducting structural interviews inorder to elicit useful information. The research finally suggests that, despite the positive effects of social media on Muslim youths’ through Facebook, Twitter, Instagram WhatsApp, e.t.c in passing meaningful information across the board its negative effect of promoting moral decadence like character assassination, media violence, nudity, obscene movies and videos that have challenged the moral values of a practicing Muslim were not to be overlooked.

In culturally diverse career settings, some designers are performing more effectively than others. The competence and intelligence behind their performance are crucial to sustainable career development in the highly competitive and globalized design industry. We believe that cultural intelligence (or CQ as a shorthand label) is highly required in such cross-cultural design situations, and it could be trained and improved through design education. Therefore, to better prepare students in design colleges for sustainable career development, we extend and assess the CQ model in design education. We begin the study by determining the demographic differences of design students in terms of CQ, then clarify associations between CQ and competitive advantage. The results of variance analyses using both a t-test and ANOVA showed that education level had a significant effect on two dimensions of CQ (cognitive and motivational CQs), whereas gender, age, and design field did not have significant effects on any dimensions of CQ. Further, step-wise regression analyses demonstrated that three dimensions of CQ (motivational, metacognitive, and behavioral CQs) had significant impacts on competitive advantage. Based on these results, theoretical and practical implications, as well as suggestions for future studies, are further discussed.

Macroeconomic Determinants

Abstract Based on panel error correction models for a sample of up to 21 countries, this paper analyses the macroeconomic determinants of house prices and rents. In accordance with the existing literature, I find significantly positive effects of per capita income and bank lending on house prices, whereas the housing stock per capita and interest rates have negative effects. For rents, the results are somewhat more remarkable, indicating that both the housing stock and interest rates have a negative effect. While contradicting conventional economic theory, the latter finding might be explained by real estate investors exploiting their pricing power with varying degree depending on the level of real interest rates. Moreover, the estimated impact of interest rates on both house prices and rents varies with structural housing market characteristics. For instance, while interest rates have a more pronounced effect on house prices in countries with more developed mortgage markets, the same does not hold for the effect of interest rates on rents.

AbstractCarboxymethyl cellulose (CMC) has been used widely to enhance dry strength of paper and uniformity of sheet in the papermaking industry. Besides these positive effects, it may affect the fines retention and dewatering processes negatively. These negative effects are mainly seen when fiber modifications with high CMC dosages are studied in laboratory scale. In this paper, the effect of fiber modification with CMC on the deposition of precipitated calcium carbonate (PCC) and on the dewatering process in the presence of cationic polyacrylamide (CPAM)/bentonite microparticle flocculation system is examined. It was determined that fiber modification with 10 mg g−1 of CMC decreased PCC deposition at the initial addition of CPAM and gave better PCC deposition at 2 mg g−1 of CPAM. It was also observed that PCC deposition on unmodified fibers is higher at lower CPAM concentration. PCC deposition was found as almost stable after a maximum value obtained at 0.5 mg g−1 of bentonite concentration for fiber modified with 40 mg g−1 of CMC. This indicates that interaction between CPAM and bentonite particles changed due to higher surface charge and CMC conformation on fibers. Results of the dewatering experiments showed that CMC modification increased the drainage time due to a denser and more plugged sheet. This negative effect was compensated with higher concentrations of CPAM and bentonite. On the other hand, dewatering is also affected by the mass ratio of CMC and CPAM, which was not the optimum one in this study at lower of CPAM. Thus, the increase in the drainage time in the presence of CMC on the fiber surface could be also caused by incorrect ratios of chemicals because the effect of CMC on the drainage time was not observed at higher concentrations of CPAM.

Positive Effect

Dissolved organic matter (DOM) can have both positive and negative effects on phytoplankton growth. The magnitude of these effects may vary depending on the source of DOM and the composition of the phytoplankton community. Here, I address the relative importance of the positive and negative effects of DOM extracts on phytoplankton growth. In short-term experiments with phytoplankton from West Long Lake, a small, moderately coloured lake in northern Michigan, U.S.A., the net effect of doubling ambient DOM on phytoplankton growth was positive. Increasing DOM concentrations from ~10 mg C·L–1 to ~20 mg C·L–1 had a negative effect on total phytoplankton growth by reducing irradiance and thus reducing the depth to which growth was positive. However, inorganic nutrients in the DOM extracts increased growth at each irradiance level. The positive effect on phytoplankton growth owing to the nutrients associated with DOM was greater than the negative effect caused by shading. Although the positive effects of allochthonous DOM inputs outweighed the negative effects for the nutrient-limited phytoplankton in these experiments, the net effect depends on the concentration and availability of nutrients associated with allochthonous DOM as well as the physiological status of the phytoplankton community.
