Can location factors moderate the effects of the demographic composition of SME's owner managers on the rate of mobile marketing technology (MMT) adoption?

Extant scholarly inquiries focused predominantly on the influence of demographic physiognomies of SMEs' owner-managers on MMT adoption, with dearth recourse to how the proxies of location factors such as workforce diversity and knowledge centres moderate and describe such relationship. To bridge that void, opinions of 345 SMEs' owner-managers in five industries situated in the state capital and commercial nerve cities of three Geo-political zones of Nigeria were purposively sampled. The analysis involved hierarchical regression and its outcome showed that diversified workforce and enhanced knowledge centres critically moderated the extant relationship between the demographic composition (age, gender, education and experience) of owner-managers and MMT adoption. Hence, location factors are moderators of the relationship between owner/managers' demographic composition and MMT adoption. Implicit is that understanding the demographic composition of owner-managers provides industry players with strong basis for competitive advantage, as well as opportunity to proactively and tactically make decisions that relate to MMT adoption.

Factors stimulating value micro-businesses attribute to digital marketing technology (DMT) adoption.

Most micro-business managers in Nigeria do not see the adoption of digital marketing technology (DMT) as vital for business. Many consider it as a precondition to support managerial or operational activities, not as a tactical and/or strategic tool. Although most studies focused on large organisations, the outcome of such research may not be appropriate to micro-businesses. This is informed by the negligence of micro-businesses' idiosyncrasies and their thought of digitalization as a precondition for managerial activities without considering the value small businesses attached to these devices in terms of aiding the use as strategic tools. This renders micro-businesses' digitalization an under-reflected phenomenon. Yet, studies spend less on examining the factors that specifically stimulate the value micro-businesses attach to these applications, leading to constant adoption and usage. Hence, there is a need for a thorough exploration of the factors that shape the value of digital marketing applications in micro-businesses in Nigeria. The study is qualitative in nature and interviews (unstructured and semi-structured) were carried out with 26 micro-businesses which was drawn purposefully from the online database and underpinned by Technology, Organisation and Environment (TOE) framework. The study revealed eleven (11) critical success factors stimulating value micro-businesses attribute to digital marketing technology (DMT) adoption. These factors include long-term functional capacity, integration capacity, expansion capacity which are related to technology context. Collective capability, collaborative experience are linked to the organisation context while adaptive training, service delivery, customer fulfilment are linked to environmental context. The study also unveiled expectancy context which is linked to budget, growth and profitability and aid in the extension of the TOE framework. This study will be of importance to academics and practitioners because it provides further awareness into DMT adoption framework, factors critical to the DMT adoption and may assist in reducing the number of resources spent in search of information aimed at helping DMT adoption by micro-businesses.

Covalent interlocking of glucose oxidase and peroxidase in the voids of paper: enzyme-polymer "spider webs".

A modular, general method for trapping enzymes within the voids of paper, without chemical activation of cellulose, is reported. Glucose oxidase and peroxidase were crosslinked with poly(acrylic acid) via carbodiimide chemistry, producing 3-dimensional networks interlocked in cellulose fibers. Interlocking prevented enzyme activity loss and enhanced the washability and stability.

Evidence for associations among somatoform dissociation, psychological dissociation and reported trauma in patients with chronic pelvic pain.

This study investigates somatoform as well as psychological dissociation, somatization and reported trauma among patients with chronic pelvic pain (CPP). Women with CPP (n = 52) who were newly referred to a gynecology department, or whose pain had resisted treatment, completed standardized self-report questionnaires and received a structured interview for DSM-IV dissociative disorders. The prevalence of dissociative disorders in the sample was very low. As hypothesized, self-reported somatoform dissociation was positively correlated with self-reported psychological dissociation and features of DSM-IV dissociative disorders; women who reported more serious psychic trauma, in particular sexual and physical abuse, experienced more somatoform and psychological dissociation than women reporting less trauma, or no trauma at all; and the association of somatoform dissociation and reported trauma was stronger than the association of psychological dissociation and trauma. Physical abuse/life threat posed by a person predicted somatoform dissociation best. The results are consistent with findings among psychiatric patients, and, therefore, strengthen the thesis that somatoform dissociation, (features of) dissociative disorder, and reported trauma are strongly intercorrelated phenomena.

Generalized dissociative amnesia: episodic, semantic and procedural memories lost and found.

OBJECTIVE: This review tests Ribot's classic twofold categorization of generalized amnesia (GA) into Type I, total loss of episodic memory, and Type II, additional more or less extensive loss of semantic and/or procedural memory. It also explores his law of regression, according to which, cast in modern terms, recovery of lost procedural and semantic memories precedes recovery of episodic memory, as well as reported aetiological factors. METHOD: Clinically and formally assessed cases of GA, published since 1845, were surveyed and further analysed. RESULTS: Over and above authentic episodic memory loss, cases differed widely in the extent of impairment of semantic and procedural memory. Recovery of semantic and procedural memory often preceded recovery of episodic memory. This particularly applied to authenticated trauma memories. To an extent, lost memories affected current functioning, and in some cases were associated with alternating dissociative personalities. Severe memory distortions upon memory recovery were not reported. Most cases were trauma or stress related, while in some cases the aetiology remained unknown. CONCLUSIONS: Contrary to the view expressed in DSM-IV, which states that dissociative amnesia pertains to an inability to recall personal information, GA may also involve loss and recovery of semantic and procedural memories. Since the loss of various memory types in GA is dimensional rather than categorical, Ribot's typological distinction does not hold. Some of the reviewed cases suggest a trauma-related aetiology. Generalized amnesia of varying degrees of severity can involve delayed retrieval of trauma memories, as well as the loss and delayed retrieval of the premorbid personality.

Somatoform dissociation discriminates among diagnostic categories over and above general psychopathology.

OBJECTIVE: The primary aim of this study was to investigate the hypothesis that somatoform dissociation would differentiate among specific diagnostic categories after controlling for general psychopathology. METHOD: The Somatoform Dissociation Questionnaire (SDQ-20), the Dissociative Experiences Scale, and the Symptom Checklist-90-R were completed by patients with DSM-IV diagnoses of dissociative disorders (n = 44), somatoform disorders (n = 47), eating disorders (n = 50), bipolar mood disorder (n = 23), and a group of consecutive psychiatric outpatients with other psychiatric disorders (n = 45), mainly including anxiety disorders, depression, and adjustment disorder. RESULTS: The SDQ-20 significantly differentiated among diagnostic groups in the hypothesised order of increasing somatoform dissociation, both before and after statistically controlling for general psychopathology. Somatoform dissociation was extreme in dissociative identity disorder, high in dissociative disorder, not otherwise specified, and increased in somatoform disorders, as well as in a subgroup of patients with eating disorders. In contrast with somatoform dissociation, psychological dissociation did not discriminate between bipolar mood disorder and somatoform disorders. CONCLUSIONS: Somatoform dissociation is a unique construct that discriminates among diagnostic categories. It is highly characteristic of dissociative disorder patients, a core feature in many patients with somatoform disorders, and an important symptom cluster in a subgroup of patients with eating disorders.

Trauma-induced dissociative amnesia in World War I combat soldiers. II. Treatment dimensions.

OBJECTIVE: This is the second part of a study of posttraumatic amnesia in World War I (WW I) soldiers. It moves beyond diagnostic validation of posttraumatic amnesia (PTA), to examine treatment findings, and relates these to contemporary treatment of dissociative amnesia, including treatment of victims of civilian trauma (e.g. childhood sexual abuse). METHOD: Key WW I studies are surveyed which focus on the treatment of PTA and traumatic memories. The dissociation-integration and repression-abreaction models are contrasted. RESULTS: Descriptive evidence is cited in support of preferring Myers' and McDougalls' dissociation-integration treatment approach over Brown's repression-abreaction model. CONCLUSION: Therapeutic findings in this paper complement diagnostic data from the first report. Although effective treatment includes elements of both the dissociative-integrative and abreactive treatment approaches, cognitive integration of dissociated traumatic memories and personality functions is primary, while emotional release is secondary.

Trauma-induced dissociative amnesia in World War I combat soldiers.

OBJECTIVE: This study relates trauma-induced dissociative amnesia reported in World War I (WW I) studies of war trauma to contemporary findings of dissociative amnesia in victims of childhood sexual abuse. METHOD: Key diagnostic studies of post-traumatic amnesia in WW I combatants are surveyed. These cover phenomenology and the psychological dynamics of dissociation vis-à-vis repression. RESULTS: Descriptive evidence is cited for war trauma-induced dissociative amnesia. CONCLUSION: Posttraumatic amnesia extends beyond the experience of sexual and combat trauma and is a protean symptom, which reflects responses to the gamut of traumatic events.

Degree of somatoform and psychological dissociation in dissociative disorder is correlated with reported trauma.

In this study, the prevalence and severity of traumatic experiences as reported by patients with dissociative disorders and with other DSM-IV psychiatric diagnoses were compared. Furthermore, the predictive value of emotional, physical, and sexual trauma with respect to somatoform and psychological dissociation was analyzed. In contrast with comparison patients, dissociative disorder patients reported severe and multifaceted traumatization. Physical and sexual trauma predicted somatoform dissociation, sexual trauma predicted psychological dissociation as well. According to the memories of the dissociative disorder patients, this abuse occurred in an emotionally neglectful and abusive social context. Pathological dissociation was best predicted by early onset of reported intense, chronic and multiple traumatization. Methodological limitations restricting causal inferences between reported trauma and dissociation are discussed.

Memories of sexual abuse: Janet's critique of Freud, a balanced approach.

Since the late nineteenth century explanations of sexual trauma have invoked unconscious mental mechanisms of forgetting. Memories have been seen as submerged only to be therapeutically recovered. Explanations and related therapies have tended to be either hotly advocated or decried, not the least were those of Janet and Freud. Once again there is a vigorous debate surrounding the status of recovered memories. This paper was undertaken to contribute to reasoned and balanced dialogue by exploring an historical dimension. There is a renaissance of interest in the oeuvre of Janet. In this article Janetian sources are examined in which he criticised Freud's views on sexual trauma and elaborated his own position, a position which is yet significant today.

Apparent amnesia on experimental memory tests in dissociative identity disorder: an exploratory study.

Dissociative identity disorder (DID; called multiple personality disorder in DSMIII-R) is a psychiatric condition in which two or more identity states recurrently take control of the person's behavior. A characteristic feature of DID is the occurrence of apparently severe amnestic symptoms. This paper is concerned with experimental research of memory function in DID and focuses on between-identity transfer of newly learned neutral material. Previous studies on this subject are reviewed and a pilot study with four subjects is described. This study is specifically concerned with the question whether self-reported asymmetries in between-identity transfer can be replicated on experimental memory tests. A secondary aim was to examine whether, in the absence of explicit transfer, implicit transfer of information would occur. The results showed that the apparent amnestic asymmetry for explicit information was substantiated in the laboratory, although at least some leakage was present between the apparently amnestic identities. No evidence was found for better performance on implicit than on explicit memory tests in the apparently amnestic identities. In the discussion, parallels between apparent amnesia in DID and state-dependent memory are drawn, and the question of simulated amnesia is addressed.

Somatoform dissociative symptoms as related to animal defensive reactions to predatory imminence and injury.

The authors hypothesized that there would be a similarity between animal defensive responses to variable predatory imminence and injury and certain somatoform dissociative symptoms of trauma-reporting patients who have dissociative disorder. As a first test of this hypothesis, 12 somatoform symptom clusters consisting of clinically observed somatoform dissociative phenomena were constructed. All clusters discriminated between patients with dissociative disorders (n = 50) and patients with other psychiatric diagnoses (n = 50). Those expressive of the hypothesized similarity--freezing, anesthesia-analgesia, and disturbed eating--belonged to the 5 most characteristic symptoms of dissociative disorder patients. Anesthesia-analgesia, urogenital pain, and freezing symptom clusters independently contributed to predicted presence of dissociative disorder. Using an independent sample, it appeared that anesthesia-analgesia best predicted presence of dissociative disorder after controlling for symptom severity. The results were largely consistent with the hypothesized similarity.

Psychometric characteristics of the somatoform dissociation questionnaire: a replication study.

BACKGROUND: The present study aimed to replicate the results of previous studies concerning the development of two versions of the Somatoform Dissociation Questionnaire. The SDQ-20 evaluates the severity of somatoform dissociative phenomena, and the SDQ-5 is a dissociative disorders screening instrument. METHODS: Thirty-one patients with dissociative disorders and 45 consecutive psychiatric outpatients with other DSM-IV diagnoses completed the SDQ-20 and SDQ-5 as well as the Dissociation Questionnaire which measures psychological dissociation. RESULTS: Mokken scale analysis showed that the items of the SDQ-20 are strongly scalable on a latent unidimensional scale. Internal consistency was high. The SDQ-20 convergent validity was supported by high intercorrelations with the DIS-Q. Dissociative patients obtained significantly higher scores than comparison patients. Patients with dissociative identity disorder scored significantly higher compared to patients with dissociative disorder nos. Sensitivity (94%) and specificity (98%) of the SDQ-5 were very satisfactory, as were, at an estimated prevalence rate of dissociative disorders of 10% among psychiatric patients, positive predictive value (84%) and negative predictive value (99%). CONCLUSIONS: All results replicated the first findings, and therefore corroborate the conclusion that the SDQ-20 and SDQ-5 are instruments of sound psychometric quality, and that somatoform dissociative phenomena are core symptoms of complex dissociative disorders.

The development of the somatoform dissociation questionnaire (SDQ-5) as a screening instrument for dissociative disorders.

Using cases of dissociative disorder (n=50) and other DSM-IV diagnoses (n=50), a somatoform dissociation self-report questionnaire was developed and its capacity to function as a screening device for dissociative disorders was analysed. A list of 75 items was constructed which, according to clinical experience and expert judgement, could reflect instances of somatoform dissociation. Statistical analyses revealed the 20 best discriminating items. Stepwise forward logistic analysis detected five items which, as a group, provided optimal discrimination between the two groups. At an estimated prevalence rate of dissociative disorders of 10% among psychiatric patients the sensitivity would be 94%, the specificity would be 96%, the positive predictive value would be 72%, and the negative predictive value would be 99%. Cross-validation in an independent sample (n=33/42) largely corroborated the initial findings. The SDQ-5 can be used as a brief screening device for dissociative disorders.

Double-blind, placebo-controlled, randomized clinical trial of homoeopathic arnica C30 for pain and infection after total abdominal hysterectomy.

Homoeopathic potencies of arnica have been used for many years to aid postoperative recovery. The effects of arnica C30 on pain and postoperative recovery after total abdominal hysterectomy were evaluated in a double-blind, randomized, controlled study. Of 93 women entered into the study, 20 did not complete protocol treatment: nine were excluded because they failed to comply with the protocol, nine had their operations cancelled or changed within 24 h and two had to be withdrawn because of the recurrence of previously chronic painful conditions. Those who did not complete protocol treatment were equally divided between the arnica (nine patients) and placebo groups (11 patients). 73 patients completed the study, of whom 35 received placebo and 38 received arnica C30. The placebo group had a greater median age and the arnica group had slightly longer operations; nevertheless, no significant difference between the two groups could be demonstrated. We conclude that arnica in homoeopathic potency had no effect on postoperative recovery in the context of our study.

The development and psychometric characteristics of the Somatoform Dissociation Questionnaire (SDQ-20).

According to 19th century French psychiatry and contemporary clinical observations, dissociation pertains to both psychological and somatoform components of experience, reactions, and functions. Because such an instrument was lacking, we aimed to develop a self-reporting questionnaire measuring what we propose to call somatoform dissociation. Patients with dissociate disorder and with other DSM-IV psychiatric diagnoses completed a list of 75 items that, according to clinical experience and expert judgment, could reflect instances of somatoform dissociation. Separate logistic analyses and determination of discriminant indices per item revealed 20 items that best discriminated between those with and without dissociative disorders. Mokken analysis showed that these items are strongly scalable on a dimensional latent scale interpreted to measure somatoform dissociation. Reliability of the scale was high. Construct validity was supported by high intercorrelations with the Dissociation Questionnaire, which measures psychological dissociation, and higher scores of patients with dissociative identity disorder compared with patients with dissociative disorders not otherwise specified. In conclusion, the Somatoform Dissociation Questionnaire (SDQ-20) is a scale of good psychometric quality, which measures somatoform dissociation. The symptoms pertain to negative and positive dissociative phenomena, which were well known in 19th century French psychiatry as the mental stigmata and mental accidents of hysteria.
