Examining the Effects of Social Media Use on Job Satisfaction in the Australian Public Service: Testing Self-Determination Theory

The purpose of this study is to investigate the relationship between social media usage for work purposes and employee job satisfaction in the public sector. Because social media is a relatively recent phenomenon, the ways in which it affects employee attitudes such as job satisfaction are not well-known. Using self-determination theory (SDT) as a framework, this study tests whether perceived competence, relatedness, and autonomy mediate the relationship between social media usage for work purposes and employee job satisfaction. Data were obtained from the Australian Public Service Commission (APSC). Overall, results generated from the structural equation models support SDT, suggesting that employees using social media for work purposes have higher self-determination and higher self-determination increases their job satisfaction. In particular, the effect of competence to job satisfaction is very high. However, while social media usage for work purposes can enhance employees’ need for autonomy and competence, it does not have any statistical effect to employees need for relatedness. In addition, social media does not have any statistical and direct effect to job satisfaction. The results suggest that social media has an indirect effect to job satisfaction. This article discusses the implications of these findings.     

Female suicides in Diyarbakir, Turkey

The aim of this study was to investigate the methods used and demographic data of women suicides by examining postmortem investigation and autopsy reports from the Branch of the Council of Forensic Medicine in Diyarbakir Province, Turkey, between 1996 and 2001. Fifty-eight percent (174/302) of suicides were females and 42% (128/302) were males. The suicide rates were similarly higher for females than for males (2.6 and 1.8 per 10,000 population, respectively). Over half of female suicides (56.3%) occurred in those under 20 years of age. The most common suicide method for women was hanging (32.2%), and for men was firearms (51.7%), but for women younger than 20 years the most frequent method was firearms. Among the female suicides, five (2.8%) were known to have attempted suicide at least once in the past. Twenty-nine women (16.7%) were documented to have any psychiatric illness. None of the women had a history of drug or alcohol abuse. A suicide note was found in only six cases (3.4%). The predominant suicide motive was family problems (in 32% or 56/174). The higher rate of suicide in females than in males, and the absolute female predominance in suicides in Diyarbakir, Turkey, are in contrast to most of the medical literature and statistical information about suicide rates by country, in which suicide rates are usually higher among males.     

Sexual variation in bucco-lingual dimensions in Turkish dentition

Sexual differences in the human skeleton have been well studied in many populations. Odontometric analysis of the human sexual variation has been less investigated and mostly derived from the dentition of extinct populations. Turkey is situated in a unique location where populations from different regions mixed with each other and created a rich gene pool. One might anticipate that modern Turkish population is composed of genes from the Balkans, Caucasus, Middle East, Iran and further as well as from ancient Romans, Byzantines, Arabs and Asiatic Turks. It is clear that contemporary Turks are a mixture of these extant and extinct people and ideal to consider it a representative study population. The purpose of this study is to analyze dental dimensions and sexual variation in living Turks and develop forensic techniques to identify human remains from the teeth when any other technique is not available or not reliable. The study is composed of Ankara University dental students (50 male and 50 female casts, average age of 21 years). Bucco-lingual breadths from 14 teeth (I1 through M2 of the maxilla and mandible) are taken from the left side and analyzed using the discriminant function statistics. An intraobserver error test did not indicate any statistically significant difference between any two measurements. Results of the study revealed that males exceeded females significantly (P<0.001) in dimensions. Coefficient of variation was most obvious in I1s and I2s of both jaws in both sexes. Stepwise discriminant function statistics suggested that upper C, and lower C and M2 are the most contributory teeth to the function. Additional formulae were calculated for situation in which only one or a fragmented jaw is available for identification. Overall accuracy of sex diagnosis ranged from 73 to 77%. In conclusion this research supports earlier studies that sexual dimorphism is population specific. While dental difference between the sexes in several human populations has been found highly dimorphic, it was not found so in Turks and accuracy of classification remained low at about 77%. The difficulty or the lack of dimorphism comes from male subjects.     

Leviathan resists: the endogenous relationship between privatization and firm performance

Using a panel dataset of privatized cement firms in Turkey, this paper models and finds support for the simultaneous relationship between privatization and firm performance. It is found that favorable short-run performance, weak market potential, higher employment, lower socio-economic development, concentrated voter preferences, and weaker representation of right-wing parties in the firms’ locality delay the timing of privatization. The paper also finds that privatization increases output in the medium-term by reducing the labor stock and promoting the adoption of more advanced technology, such that production shifts from constant to decreasing returns to scale.     

Democracy and Economic Growth: A Meta-Analysis

Despite a sizeable theoretical and empirical literature, no firm conclusions have been drawn regarding the impact of political democracy on economic growth. This article challenges the consensus of an inconclusive relationship through a quantitative assessment of the democracy-growth literature. It applies meta-regression analysis to the population of 483 estimates derived from 84 studies on democracy and growth. Using traditional meta-analysis estimators, the bootstrap, and Fixed and Random Effects meta-regression models, it derives several robust conclusions. Taking all the available published evidence together, it concludes that democracy does not have a direct impact on economic growth. However, democracy has robust, significant, and positive indirect effects through higher human capital, lower inflation, lower political instability, and higher levels of economic freedom. Democracies may also be associated with larger governments and less free international trade. There also appear to be country- and region-specific democracy-growth effects. Overall, democracy's net effect on the economy does not seem to be detrimental.     

Differences in Handwritings of Schizophrenia Patients and Examination of the Change after Treatment

The aim of this study was to analyze the differences between the handwritings of schizophrenia patients and healthy subjects in addition to the changes that occurred in schizophrenia patients' handwriting in response to the treatment. The test subjects were 29 schizophrenia patients and 29 healthy individuals with the same age, gender, and dominant hand. The changes in the handwritings were examined according to 14 different parameters. On the day of admittance, the percentage of extra letters was 16.7%, and after 7–10 days of hospitalization, it rose to 33.3%. The percentage of skipped words decreased from 29.2% to 16.7% after 7–10 days of hospitalization, and to 10% after 3 weeks. The letters written by schizophrenia patients are significantly larger in height and width compared to the control group. The schizophrenia patients showed a higher incidence of crossed-out letters, adding extra words, missing punctuation as well as missing words.     

Intracranial sewing needle in a man with seizure: a case of child abuse?

Physical abuse in infancy can cause persistent neurological deficits. Although intracranial foreign bodies are generally secondary to penetrating trauma or surgical procedures, rarely they also occur as a result of child abuse. A 32-year-old man presented with the complaint of generalized tonic clonic seizures to the Neurology Department of Marmara, University Hospital. Computerized tomography (CT) scan revealed a sewing needle located within the temporal lobe. The location and the position of the needle suggested that it must have been introduced in infancy through the lamdoid suture before the closure of it, as an unsuccessful deliberate homicide attempt or accidental injury.     

Whole Plastome Sequences of Two Drug-Type Cannabis: Insights Into the Use of Plastid in Forensic Analyses

DNA is one of the fastest growing tools in forensic sciences, increasing reliability in forensic reports and judgments. The use of DNA has increased in different areas of the forensic sciences, such as investigation of plant species, where plastid DNA has been used to elucidate and generate evidence in cases of traceability of genetically modified and controlled plants. Even with several advances and the practice of using DNA in forensic investigations, there are just few studies related to the identification of genetic tools for the characterization of drug and nondrug-types of Cannabis. Herein, the whole plastomes of two drug-type Cannabis are presented and have their structures compared with other Cannabis plastomes deposited in the GenBank, focusing in the forensic use of plastome sequences. The plastomes of Cannabis sativa “Brazuka” and of the hybrid Cannabis AK Royal Automatic presented general structure that does not differs from the reported for other C. sativa cultivars. A phylogenomic analyses grouped C. sativa “Brazuka” with the nondrug C. sativa cultivars, while the hybrid Cannabis AK Royal Automatic placed isolated, basal to this group. This suggests that the analysis of plastomes is useful toward genetic identification of hybrids in relation to C. sativa.
